These amplifiers are designed to operate from 2.7V to 12V (±6V) supplies. The common mode voltage range extends below the negative rail and the output provides rail-to-rail performance. The FHP3130, FHP3230, and FHP3430 are designed on a complimentary bipolar process and provide 170MHz of band- width and 110V/µs of slew rate at a supply voltage of ±5V. The combination of low power, rail-to-rail performance, low voltage operation, and tiny package options make these amplifiers well suited for use in many general purpose high speed applications. These amplifiers also provide excellent video specifications. They offer extremely low differential gain and phase (0.008%/ 0.01˚) and 0.1dB gain flatness to 16MHz for superb standard definition video performance. Their output drive capability effort- lessly supports 4 video loads. Driving Capacitive Loads The Frequency Response vs. CL plot on page 8, illustrates the response of the FHP3230 Family. A small series resistance (Rs) at the output of the amplifier, illustrated in Figure 27, will improve stability and settling performance. Rs values in the Frequency Response vs. CL plot were chosen to achieve maxi- mum bandwidth with less than 1dB of peaking. For maximum flatness, use a larger Rs. Figure 27. Typical Topology for Driving Capactive Loads Power Dissipation The maximum internal power dissipation allowed is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150°C for an extended time, device failure may occur. The FHP3130, FHP3230 and FHP3430 are short circuit protected. However, this may not guarantee that the maximum junction temperature (+150°C) is not exceeded under all conditions. RMS Power Dissipation can be calculated using the following equation: Power Dissipation = Is * (Vs+ - Vs-) + (Vs+ - Vo(RMS)) * IOUT(RMS) Where Is is the supply current, Vs+ is the positive supply pin voltage, Vs- is the negative supply pin voltage, Vo(RMS) is the RMS output voltage and IOUT(RMS) is the RMS output current delivered to the load. Follow the maximum power derating curves shown in Figure 28 below to ensure proper operation. Figure 28. Maximum Power Derating Overdrive Recovery For an amplifier, an overdrive condition occurs when the output and/or input ranges are exceeded. The recovery time varies based on whether the input or output is overdriven and by how much the ranges are exceeded. The FHP3130/3230/3430 will typically recover in less than 50ns from an overdrive condition. Figure 29 shows the FHP3230 in an overdriven condition. Figure 29. Overdrive Recovery Composite Video Summer The bandwidth and differential gain/phase performance of the FHP3130/3230/3430 amplifiers make them well suited for video applications. Figure 30 shows a typical Composite Video Sum- mer. The high output current capability allows for driving multi- ple video loads. Figure 31 shows the resulting differential gain/ phase of this 3-amp configuration driving 4 video loads, 37.5Ω. + - Rf Rg Rs CL RL 1.6 1.4 1.2 1.0 0.8 0.6 0.4 0.2 -40 Ambient Temperature (°C) 0 -20 0 20 40 60 80 TSSOP-14 SOIC-14 SOIC-8 MSOP-8 SOT23-5 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 0 Time (µs) -0.5 0.2 0.6 0.4 0.8 10 1.2 1.4 1.6 1.8 Output Input Vs = 3V G = 5 RL = 2k Ω Rf = 1k Ω |
